MOUNTING FOR THIRD RAILS.

SPECIFICATION forming part of Letters Patent No. 605,260, dated June 7, 1898. Application filed November 5, 1897. Serial No. 657,510. (No model.)

To all whom it may concern.-

Be it known that I, SIDNEY HOWE Snorer, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented a new and useful Mounting for Third Rails, of which the following is a specification.

This invention relates to mountings for third rails.

The object of the invention is to provide a mounting for third or contact rails in electricrailway equipments wherein the third or contact rail is efficiently supported and insulated.

The invention consists, substantially, in the construction, combination, location,'and rel ative arrangement of parts, all as will be hereinafter set forth, as shown in the accompanying drawing, and finally specifically pointed out in the appended claims.

The accompanying drawing illustrates a transverse section of the road-bed of an elec-,

tric railway, showing the mounting for the third or contact rail in accordance with the principles of my invention.

In the drawing, A designates a cross tie or beam of the road-bed, B the track or service rails, and C the third or contact rail. In order to efficiently support and insulate this third or contact rail, I support the same on short transverse bars D. Attached to or formed with the ends of this bar are the bell or cup shaped castings E. The standards F, suitably mounted on and secured to the cross beams or sills of the road-bed, are arranged to project into the bell or cup shaped castings E. To afford proper insulation, these bell or cup shaped castings are filled with suitable insulating material I-such, for instance, as rubber, wood, sulfur, or the likeand' the ends of standards F are received and embedded in this insulating material. In order to still further aid the above-described arrangement in properly and efficiently insulating the third or contact rail, I interpose between the rail 0 and,the supporting-bars D a strip or board of suitable insulating materialas, for instance, a Wooden board suitably tarred or waterproofed. It is evident that a rubber strip or other suitable insulating material is equally well adapted for this purpose. The strip H is laid upon the supports D parallel with the rail O,Which is placed thereon. From I vention is concerned.

this arrangement it will be seen that the third or contact rail O is doubly insulated, first by the insulating-strip H and then by the insulated supports of bars D.

In order that the motor, truck-frame, brakerigging, and the like may not be obstructed by the contact-rail C, it is important that the top surface of said rail be as low down as possible. To secure this end, the bell or cup shaped portions E are arranged to extend away from said bar on one side thereof, thereby imparting a U shape in longitudinal section to said bar, and hence bringing the top surface of said rail into'the same horizontal plane, or nearly so, with the tops of the traction or service rails B. l I

Of course it will be obvious that the third rail may be arranged between the service or' traction rails, as shown, or in any other suitable or convenient relation with respect thereto, the particular relative location of said rail being unimportant so far as the present in- While the invention is adapted for use generally in electric railways employing third or contact rails, it is particularly designed for use in connection with elevated-railway structures.

Having now set forth the object and nature of myinvention and an arrangement embodying the same, what I claim as new and use ful and of my own invention, and desire to secure by Letters Patent of the United States,

1. In a mounting for third or contact rails, the combination with standards, a bar supported by but insulated from said standards, an insulating strip or board supportedby said bars and arranged to extend lengthwise with respect to the third or contact rail, said rail being arranged to rest on said strip or board, as and for the purpose set forth.

2. A supporting-bar fora third or contact rail having bell or cup shaped castings at the end thereof, insulating material arranged in said castings, and supporting-standards ar- 1 l'OO arranged in said castings, and supportingstandards arranged to be received in said insulating material, as and for the purpose set forth.

4. The combination with a third or contact rail, a supportingbar therefor having inverted-bell or cup shaped castings arranged to project from the ends and on the same side thereof, insulating material arranged in said 10 castings, supporting-standards arrangedto 2 r v r 605,260 4 be received in said insulating material, and an insulating-strip interposed between said bar and rail, as and for thepurpose set forth.

In Witness whereof I have hereunto set my hand, this 1st day of November, 1897, in the t5-
